Deep caries, an existing faulty restoration, or a collapse of edentulous alveolar ridge may not only affect the amount of coronal support but may also leave large deformities to the fixed prosthesis.
Therefore, to repair of lost oral structures and prevention of unacceptable esthetic deformities, surgical crown lengthening or edentulous ridge augmentation were performed.
In this paper, we present a case which underwent a 2-step surgical procedure, consisting of a crown lengthening with apically positioned flap and a edentulous ridge augmentation with subepithelial connective tissue graft to removal of subgingival root caries, to improve asymmetrical or unesthetic gingival topography, and to correct the form of ridge.
In consequence of these periodontal reconstructive surgery, we attained the establishment of more idealized ridges prior to placing fixed bridge in the maxillary anterior portion.
